WINDOW VENTILATOR Filed Aug. 11, 1937 wlagpllllllllz ("HA/u 5.5 A. A/vamso/v INVENTOR ATTORN EY Patented Sept. 13, 1 938 UNITED STATES PATENT OFFICE WINDOW VENTILATOR York Application August 11,

'7 Claims.

My invention relates to window ventilators and has particular reference to ventilating deflectors or shields placed in the lower portions of window's.

Window ventilators of this type usually have deflectors made of glass plates held in place by end brackets fastened to window frames. When fitting a ventilator to a window, the glass plate must be therefore cut to the exact width between the brackets, this width more or less varying for different windows. Such an operation is highly objectionable, however, rendering the installation difiicult and requiring services of an expert glass cutter. In order to avoid this difiiculty, two glass plates are sometimes used, telescopically sliding side by side. This arrangement is also objectionable, however, two panes of glass being more expensive and requiring special adjustable braces or rods on top and bottom of the plates, and being less satisfactory from the standpoint of appearance than a single plate.

I have found, however, that it is possible to make horizontally adjustable ventilators, using glass plates of a standardized length and providing adjustment in the end brackets. Windows in ordinary houses vary in width, as a rule, by afew inches only, say between 36 and 40 inches. By making the glass plates 38 inches long, for instance, and the end brackets 3 or 4 inches deep, I can provide a ventilator readily attachable to any ordinary window. An object of my invention is therefore to provide a ventilator of a standardized construction which can be attached to any ordinary window by merely screwing or nailing the end brackets to the window frame.

Another object of my invention is to provide end brackets with detachable holders for the glass plate. By making the holders detachable not only their manufacturing is simplified, but their handling for shipmentis facilitated, the knocked down parts occupying much less space than the assembled brackets.

Another object of my invention is to provide means for retaining the glass plate in the end holders in a fixed position after the brackets have been fastened to a window frame. For this purpose I provide adjustable blocks in the holders resting against the ends of the glass plate, or adjustable screws or plugs fitted in slots or holes in the holders.

Still another object of my invention is to provide sliding caps for the upper portions of the end glass holders, the caps not only attractively 1937, Serial No. 158,480

covering the holders but also serving as clamps to hold the sides of the holders together, the holders being preferably made in the form of .p-shaped pieces of sheet metal.

My invention is more fully described in the accompanying specification and drawing in which'- Fig. 1 is a perspective view of my ventilator attached to an ordinary window.

Fig. 2 is a perspective View of an end bracket with a glass plate holder in a detached position.

Fig. 3 is a sectional detail view of the bracket with the glass plate and a spacing block inside.

Fig. 4 is a view taken on the line 4-4 of Fig. 3.

Figs. 5 and 6 are detail views of a modified arrangement for retaining the ends of the glass plate.

Figs. 7 and 8 are similar detail views of another modification.

,Fig. 9 is a detail view of still another modification for holding the ends of the glass plate in position.

Figs. 10 and 11 are detail views of still another modification.

My window ventilator consists of end brackets shown indetail in Fig. 2 which may be formed of two pieces i and 2 each pivoted together at 3 and telescopically adjustable to different angles of opening as described'in my Patent No.2,016,764. A lug 4 on one piece and a hook 5 on the other prevent the pieces from becoming entirely separated. The outer piece or sector 2 has a flange 6 with rectangular apertures I, the inner piece l having holes 8 for attaching the brackets, which are right and left, to the inner sides of a window frame 9 by screws H3. The apertures l are engaged by resilient hooks ll formed in U-shaped holders l2 for a glass plate l3. The holders are made of sheet metal and the hooks l l are stamped out to register with the apertures 1. Thus the brackets and the holders can be easily assembled together or taken apart to be packed for shipment. The sides of the holders are spaced apart so as to provide room for the ends of the plate [3, the width of the sides of the holders being sufiicient to allow for ordinary variations in the width of the windows. I have found that holders 3 or 4 inches wide can be used with a large number of windows, having usually from 36 to 40 inches in width, the glass plate being about 38 inches long. In order to prevent longitudinal shifting of the plate after its assembly, I provide spacing blocks M in the holders resting against the ends of the plate [3. These blocks are preferably made of wood or similar material which can be easily trimmed by an ordinary penknife or similar tool. The blocks need not fill the holders through the full length and short pieces at the bottom of the holders are suflicient. The top edges -l5 and I6 diverge outwardly or flare out so as to make room for a thick upper edge of the glass plate as the latter are usually furnished for this purpose, representing edge portions of sheets made on glass sheet drawing machines.

A cover I1 is slidably fitted over the diverging V edges of the holder, the sides of the cover converging so as to engage the diverging edges as shown in Fig. 4. The cover therefore not only encloses the upper portion of the holder but alsoholds its sides tightly together against the glass plate. The portions l5 are cut away at the outer ends as shown in Fig. 2 at 18 to make room for corresponding tongues or lugs IS on the flanges 6, this arrangement enabling the covers I! to hold the pieces l2 more firmly against the flanges 6.

A modified arrangement for retaining the ends of the glass plate is shown in F'ugs. 5 and 6 showing portions of a U-shaped holder 20 having a horizontal slot '21 for a screw 22 held by a nut 23. The screw has a head 24 resting against .the end of the glass plate and a square portion 25 sliding in the slot and preventing the screw from rotation. The screws at both ends of the ventilator, after being tightened against the ends of the glass plate, prevent the latter from moving or shifting longitudinally.

Another modification is shown in Figs. '7 and 8. A holder 26 has an outwardly extending recess 21 with a slot 28 for a square head 29 of a screw 30. A nut 3| is used for tightening the screw. The head 29 is slidably fitted in the recess and therefore cannot turn when the nut is turned.

In a modification shown in Fig. 9 the holder 32 has holes 33 for a plug 34 which also rests against the ends of the glass plate.

It is understood that my ventilator can be used with any suitable end brackets, not necessarily of the telescoping type, and single sector-shaped or triangular pieces of sheet metal may be used with flanges 6 for'the holders.

In a modification shown in Figs. 10 and 11 the rear side of a U-shaped holder l2 has a flat spring 36 pivoted at 31 and having a head 38 with a handle 39 and a pin-shaped lug 40' fitting in holes 41 arranged concentrically with the pivot 31. The lug 40 extends inside the holder and forms a stop for the end edge of the glass plate I3. The plug or lug 40 can be pulled out against the tension of the spring and replaced in any of the holes 4| for retaining the plate I3 in its middle position in the brackets.
